ROLL FOR OPERATING UPONBOQT-S AND Specification of Letters Patent.

Patented Feb. 2'7, 1917.

Application filed June 10,1915. Serial No. 33,380.

To all whom it may concern:

Be it known that 1, WILLIAM H. BURKE, a citizen of the United States,residing at Haverhill, in the county of Essex. and State ofMassachusetts, have invented certain new and useful Improvements inRolls for Operating upon Boots and Shoes; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

The present invention relates to rolls for operating upon boots andshoes, and more particularly to rolls employed for leveling the soles ofboots and shoes.

It will be obvious to those skilled in the art that as a finished soleafter it has been incorporated in a boot or shoe, varies both in widthand transverse curvature throughout the length of the sole, it isdesirable to provide means for adjusting the leveling roll in order thatthe roll shall operate most efficiently upon each portion of the shoesole.

The object of the present invention is to provide certain improvementsin a roll for operating upon boot and shoe soles which enables both thesize and shape of the roll to be varied. feature of the inventioncontemplates the provision of a roll for operating upon boot and shoesoles comprising a continuous unbroken sole engaging surface extendinglengthwise from end to end of the roll, and means for varying thelongitudinal contour of the roll. In the simplest and most efficientform of the invention which has yet been devised the roll consists of aseries of sole engaging ribs extending continuously from end to end ofthe roll, and means engaging with the ribs for varying the longitudinalcontour of the roll.

Still further features of the invention consist in certain novelfeatures of construction, combinations and arrangements of- With thisobject in view atrating in dotted outlinethe position of a shoe solewith relation to the roll.

According 4 to the present invention the longitudinal contour of theleveling roll may be. adjusted or varied as desired and the diameter ofdifferent portions of the roll is also varied in order to permit theroll to operate most efficiently upon both the ball and shank portionsof a shoe sole. In the illustrated embodiment of the invention a seriesof flexible ribs are secured to a rotary hub between their ends and apair of oppositely disposed spreader members ,projectvwithin the ends ofthe ribs to determine the separation of the ribs and the consequentcontour of the roll. The spreader members are conveniently actuated by acommon control which causes the members to. be moved simultaneouslytoward and from one another to insure an even spacing of the ribs attheir opposite ends. The roll comprises a series of ribs 2, eachsupported between their ends upon a rotary hub 4 and each rib extendingcontinuously from end to end of the roll. Each rib is secured rigidly tothe hub midway of its ends by a fastener member 5 and with this.construction it will be obvious that as the central portions of the ribsare secured to the hub, the diameter and shape of the central portion ofthe roll will be fixed. The hub a is secured to a shaft 7 journaled inthe upper ends of stationary arms 8 and 9 and having a driving pulley 10secured to one end by which the roll is conveniently actuated to beatout and level the sole of a shoe. The Separation of the ends of theribs. and the longitudinal contour of the roll is varied by a pair ofoppositely disposed spreader members 12 which are splined upon the shaft7 and are provided with peripherally grooved hubs 14 which areoperatively connected with actuating provided with a second arm 17extending therefrom, the two arms 17 being interconnected at their endsby gear teeth 18. The arms are conveniently actuated by a treadle rod 20connected to one of the arms 17.

With this construction it will be obvious that the longitudinal contourof the leveling roll may be varied as desired and this is accomplishedwithout interrupting the continuity of the sole engaging surfaces, orwithout forming any break in the leveling roll which would tend to maror disfigure the surface of the sole.

While it is preferred to employ the specilic construction andarrangement of parts shown and described, it will be understood thatthis construction and arrangement is not essential except so far asspecified in the claims, and may be changed or modified withoutdeparting from the broader features of the invention.

The -invention having been described, what is claimed is 1. A roll foroperating upon boot and shoe soles, comprising a series of sole engagingribs each extending continuously from end to end or" the roll, and meansengaging with the ribs for varying the longitudinal contour of the roll.

2. A roll for operating upon boot and shoe soles, comprising a series ofribs extending continuously from end to end of the roll, means forsupporting the ribs in spaced relation to one another between theirends, and means for spreading the ends of the ribs apart to vary thelongitudinal contour of the roll.

3. A roll for operating upon boot and shoe soles, comprising a shaft, aplurality of ribs supported upon the shaft in spaced relation to oneanother to present a substantially cylindrical surface to the shoe sole,and means for separating the ends of the ribs in a radial direction tovary the'longitudinal contour of the roll.

a. A leveling roll comprising a series of ribs extending lengthwise ofthe roll, means for supporting the ribs midway of their ends in spacedrelation to one another, and means engaging with the ribs to vary thediameter of the roll at the ends.

5. A roll for operating upon boot and shoe soles, comprising, a rotaryhub, a series of flexible ribs secured to the hub midway of their ends,and a spreader member projecting within the ends of the ribs todetermine the separation of the ribs and the contour of the roll.

6. A roll for operating upon boot and shoe soles, comprising, a rotaryhub, a series of ribs secured to the hub midway of their ends, aspreader member projecting within the ends of the ribs, and means formoving the member lengthwise of the roll.

7. A roll for operating upon boot and shoe soles, comprising, a seriesof ribs extending lengtlnvise of the roll, means for support ing theribs midway of their ends, a pair of oppositely disposed spreadermembers projecting within the ribs at the opposite ends, and means forsimultaneously moving the sareader members toward and from one another.I

8. A roll for operating upon boot and shoe soles, comprising, a shaft, ahub secured to the shaft, a series of flexible ribs secured to the hubmidway or" their ends, a pair of conical members slidingly mounted uponthe shaft and projecting within the opposite ends of the ribs, armsengaging with the conical members, and means for simultaneouslyactuating the a ms to move the conical members toward and from oneanother.

9'. A roll for operating upon boot and shoe soles, provided with aseries of beating out surfaces extending lengthwise of the roll andhaving a fixed diameter at its central portion, and means for varyingthe diameter of the outer ends of the roll.

10. A roll for operating upon boot and shoe soles, having incombination, a series of ribs extending lengthwise of the roll, meansfor supp rting the ribs midway of their ends in fixed relation to oneanother, and means for varying the separation of the ends of the ribs.

11. A roll for leveling boot and shoe soles, comprising a continuousunbroken sole enging surface extending lengthwise from end to end of theroll, and means for varying the longitudinal contour of the roll.

12. A roll for leveling boot and shoe soles, having in combination, acentral portion, and tapered members movable toward and from the centralportion to vary the longitudinal contour of the roll.
